traceoptions (Services L2TP)

Syntax

Hierarchy Level

Description

Define tracing operations for L2TP processes.

Options

debug-level level—Trace level for PPP, L2TP, RADIUS, and UDP; this option does not apply to L2TP on MX Series routers:

• detail—Trace detailed debug information.

• error—Trace error information.

• packet-dump—Trace packet decoding information.

file filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks. All files are placed in the directory /var/log.

files number—(Optional) Maximum number of trace files to create before overwriting the oldest one. If you specify a maximum number of files, you also must specify a maximum file size with the size option.

• Range: 2 through 1000

• Default: 3 files

filter—Additional filter to refine the output to display particular subscribers. Filtering based on the following subscriber identifiers simplifies troubleshooting in a scaled environment.

• protocol name—One of the following protocols; this option does not apply to L2TP on MX Series routers:

  • l2tp

  • ppp

  • radius

  • udp

• user user@domain—Username of a subscriber; this option does not apply to L2TP on M Series routers. Optionally use an asterisk (*) as a wildcard to substitute for characters at the beginning or end of either term or both terms.

• user-name username—Username of a subscriber; this option does not apply to L2TP on MX Series routers.

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:

• all—Trace all operations.

• configuration—Trace configuration events.

• events—Trace interface events.

• general—Trace general events.

• gres—Trace GRES events.

• init—Trace daemon initialization.

• ipc-rx—Trace IPC receive events.

• ipc-tx—Trace IPC transmit events.

• memory—Trace memory management code.

• message—Trace message processing code.

• packet-error—Trace packet error events.

• parse—Trace parsing events.

• protocol—Trace L2TP events.

• receive-packets—Trace received L2TP packets.

• routing-process—Trace routing process interactions.

• routing-socket—Trace routing socket events.

• session-db—Trace session database interactions.

• states—Trace state machine events.

• timer—Trace timer events.

• transmit-packets—Trace transmitted L2TP packets.

• tunnel—Trace tunnel events.

interfaces interface-name—Apply L2TP traceoptions to a specific services interface. This option does not apply to L2TP on MX Series routers.

• debug-level level—Trace level for the interface; this option does not apply to L2TP on MX Series routers:

  • detail—Trace detailed debug information.

  • error—Trace error information.

  • extensive—Trace all PIC debug information.

• flag flag—Tracing operation to perform for the interface. This option does not apply to L2TP on MX Series routers. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:

  • all—Trace everything.

  • ipc—Trace L2TP Inter-Process Communication (IPC) messages between the PIC and the Routing Engine.

  • packet-dump—Dump each packet content based on debug level.

  • protocol—Trace L2TP, PPP, and multilink handling.

  • system—Trace packet processing on the PIC.

level—Specify level of tracing to perform. The option you configure enables tracing of events at that level and all higher (more restrictive) levels. You can specify any of the following levels:

• all—Match messages of all levels.

• error—Match error messages.

• info—Match informational messages.

• notice—Match notice messages about conditions requiring special handling.

• verbose—Match verbose messages. This is the lowest (least restrictive) severity level; when you configure verbose, messages at all higher levels are traced. Therefore, the result is the same as when you configure all.

• warning—Match warning messages.

• Default: error

match regular-expression—(Optional) Refine the output to include lines that contain the regular expression.

no-remote-trace—Disable remote tracing.

no-world-readable—(Optional) Disable unrestricted file access.

size maximum-file-size—(Optional) Maximum size of each trace file. By default, the number entered is treated as bytes. Alternatively, you can include a suffix to the number to indicate kilobytes (KB), megabytes (MB), or gigabytes (GB). If you specify a maximum file size, you also must specify a maximum number of trace files with the files option.

• Syntax: sizek to specify KB, sizem to specify MB, or sizeg to specify GB

• Range: 10240 through 1073741824

world-readable—(Optional) Enable unrestricted file access.

Required Privilege Level

trace—To view this statement in the configuration.

trace-control—To add this statement to the configuration.
